Application filed March 6, 1922.

To all whom it may concern:

Be it known that we, CANUTE H. Fons- BERG and CARL W. Fonsnnne, citizensof the United States, residing at Patton, in the county of Ca'mbria andState of Pennsylvania, have invented certain new and useful Improvementsin Scraper Attachments for Various Brushes, of which the following is aspecification, reference being had to the accompanying drawings.

It is the purpose of the present invention to provide an improved knifeor scraper, for attachment to various brushes, such as scrub brushes,stove brushes, paper hanger brushes and paint brushes and the like, forthe removal of dirt and other foreign matter, before scrubbing, orpolishing stoves, or before hanging paper, and before painting orotherwise decorating surfaces.

Very often when scrubbing, painting or performing work of a similarcharacter, it is necessary to remove some foreign matter, dirt or thelike that would if left would not present a neat appearance.

Therefore the present invention further aims to provide an improvedknife or scraper applicable to the handle of any kind of brush, and theblade of which can be easily and conveniently opened at any time, forthe purpose of removing dirt and other foreign matter.

Still another purpose is the provision of a knife or scraper attachmentof this character comprising a folded metal piece comprising opposedwalls secured to the wood port-ion of the brush, together with a bladeor knife pivoted between the walls of the folded metal strip, said bladebeing provided with means, such as a roll on the rear edge of the blade,so that its end may engage a notch of one of the sides or walls of thefolded metal strip, in order to limit the blade in its open position.

A still further purpose is the provision of a roll on the rear edge ofthe blade, between which and the blade the edge of the notch of one wallof the holderfor said blade engages, for the purpose of limiting theblade in its open position, and thereby acting to relieve the lateralstrain upon the pivot of the blade.

It is to be understood that the particulars herein given are in no waylimitat-ive and that while still keeping within the scope of theinvention, any desired modifications of Serial No. 541,556.

detail and desired proportions may be made in the apparatus according tocircumstances.

The invention comprises further features and combination of parts, aswill be hereinafter set forth, shown in the drawings and claimed.

In the drawings:

Figure 1 is a view' of'the improved knife or scraper attachment asapplied to the wood portion ofthe brush;

Figure 2 is a longitudinal sectional view through the same on line 22 ofFigure 1;

Figure 3 is a view showing the knife or scraper as applied to the handleof another form of brush;

Figure 4 is an enlarged detail perspective view of the pivotalconnection between the blade and the opposite sides of the metal strip,between which the blade ispivoted, showing theroll which cooperates withthe notch in one wall of the metal holder for the blade;

Figure 5 is a cross sectional view on line -5-5 of Figure 4.

Referring to the drawings, 1 designates the handle of a brush, whetherit be a scrub 7 folded strip of metal 2. This strip of metal is foldedupon itself as at 3, and between the plies of the folded piece, adjacentthe bight 7 thereof is a metal filler 4. Passing through the plies ofthe metal strip and through the filler, and secured in the wood portionor handle of the brush are screws 5, which secure the folded metal stripto the handle. Pivoted between the sides of the folded metal strip as at6 is a knife or blade 7. This blade or knife may be any suitable shape,or proportions, preferably short and broad as illustrated, and isprovided with sharp scraping edges 8 and 9, for the purpose of removingdirt and other foreign matter from a surface which is to be scrubbed,painted, papered or otherwise covered.

The rear edge of the blade or knife has an extension 10, which is rolledupon itself, and projects laterally fromthe blade. This roll may be anysuitable length, preferably as shown, and where one end of the wall ofthe roll projects or turns toward the body of the blade, the edge 11 ofa notch 12 of one of the sides of the metal strip engages. One edge ofthe notch is, curved as shown at 13, constituta cam, over wh ch the edgeportion 01 one end of roll operat s, so that one edge of the end of theroll may engage the shoulder 14 of the notch, thereby limiting the bladeor knife in its open position. Before the end of the roll engages theshoulder of the notch, it is necessary to force the roll over the curvedcam edge of the notch. ln :tact'duo to the extension being turned uponitself to form the roll, and since the end the ere tension which formsthe roll is not attached to the body of the knife, there is a certaindegree of resiliency ot the tern .nal of the extension forming the roll,the more the roll will. act to cam over the curved. edge of the notoii,in order to permit the edge oi the end of the roll to contact with theshoulder of the notch, and hence limit the blade or knife in its openposition. I

roni the foregoing it will be seen that there has been devised a simple,ei'licient and practical scraper or knife to be used in connection withbrushes of the various characters herein named, for the purpose oi.ettectively ren'ioving the dirt or other foreign matter from a surfacewhich is to be painted, papered or otherwise covered.

The pivoted end of the blade 7 is pro vided with a depression 15, andone of the sides of the piece or strip of metal '2 is also provided witha depression 16. This depression 16 causes a bulge to form on the innerface or the side of said strip of metal, adapted to engage thedepression 15 When the blade or knife is open, thereby assistingmaterially in holding the knife in an open position.

It will be noted that since the roll or er:- tension 10, where itengages the edges 11 and 13, is more or less resilient, and since thisresilient portion bears upon one side of the sheet metal strip, thebulge caused by the depression 16 will engage the depression 15,assisting materially in holding the blade in an open position, andsecurely latched in such position. In fact the roll or extension the 10where it engages the notch 12 has an action oi bearing down upon oneside of the sheet metal strip or strap, and acts to draw the two piecestogether, to insure holding the bulge in engagement with said extension.

The invention having been set forth, what is claimed is 1. in a scraperattachment, a folded strip of metal adapted to be mounted on a body,means for spacing the plies of the strip, a scraping blade pivotedbetween the plies, one end of one of the plies having a notch, and aroll extending longitudinally along the back edge of the blade andhaving a yield.- able portion to engage the shouldered end of the notchto limit the blade in. its open position.

2. The combination with a body, of a metal strip folded upon itself andsecured to said body, the end of one ply of the metal strip having anotch provided with a shoul der, blade pivoted between the plies of saidmetal. strip, said. notch. having a cam edge, and a roll carried by therear edge of the blade and having a yieldable portion to cooperate withthe cam edge when opening the blade, whereby the end of said yieldableportion of the roll may contact with the notch and limit the blade inits open position.

The combination of a scraper adapted to be mounted on a body, comprisinga holder to be secured to said body, said holder comprising oppositeplies, the edge of one end of one ply having a notch, a blade pivotedbetween the plies of said holder and having a roll at one edge providedwith a spring extension, adapted to cam over one edge of said notch,whereby it may engage the shoulder of the notch to limit the blade inits open position.

in testimony whereof we hereunto afiiX our signatures.
